To all whom it may concern.-

Be it known that we, Donn E. FEL'i` 'and CHARLES P. WnTMona, citizens of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented 'a new and useful Improvement in Tabulating- Machines, of which the following is a speci-V fication.

This invention is a modification of and in some .respects an improvement u on the construction of listingmachines s own 1n Patent No. 749,177, dated January 12, 1904 to D.- E. Felt. f

It embodies an improved construction of spring cushioning mechanisms for avoiding shocks and jars to the mechanism from the power lever; an fimprovedconstruction of governor for 'regulating the speed of the mechanism; an improved construction of cancel' i mechanism, adapted to operate mitomatically on the printing 'oi the total; means for preventing t e cancellation whenever desired; means 'forpreventing changes in the lever whereby the ltotal printing is caused pending full strokes of the power device' means for preventing disableV printing b the printing hammers, and other eatures ely invention, all of which are fully set forth below. Y

Our machine embodies-any desired number of denomi'national and in each denomination arenine digital keys shown at 2O arranged in rows extending backward from the iront of the machine. The stems of these keys extend downward between pairs of ide plates 21 and 22-and are provided rings 24 on the plates 22. The

res showing plates 2i an 22 of cach section are preferably united at theirends and by posts 27 through which cross bars 23 may extend. Y

Below each denominational series of keys is a kellocking plate 28 shown in Figs. 3 and 4.v andV 'nged at its ends in the ends 26 of the key frames as seen at 29 in the same fi res,

so that the plate may be swung latere y bvthe keys when the latter are depressed, eac plate being rovided with s rings press' it toward the Ycys, so that w en deflected y the descent of any key, the plate will swin back under the power of its sprio and loc the'key as soon as its bent end as passed below the plate. This construction is clearly illustrated in the Felt patent above referred to 'at 13, and need not be further described.. The keys which are locked byA Athese plates remain under their control until released by the striking of another key in the same denomination, 0I' by the o ration of the reieasing lever or inthe ad ing operation. Directly below each denominational IOO row of keys is also located a bar 31 having freedom to .move longitudinally. It is supported upon its ends upon dolly rolls 32 and 33 and is provided with nine inclines or cams 34, one below each key embraced in the denomination, and the inclines are raduated in length according to the power o the keys under which they are located, the incline under the 9 key being long, and that under the 8 key being somewhat shorter and so on gradually diminishing in length to the incline upon the units kev which is quite short. The inclines are located directly under the keys so that when the latter are struck, they come against the iiiclines and give longitudinal motion to the bar for a distance corresponding to the length of the incline. The variable and aduated movementsof the bar received bm the keys determine the action of the adding and printing mechanism, as Will be understood later on. The bars are returned to their normal ositions by springs 35 which are attached to egs 36 on the frame members 22 and pins 37 on the bars, but are detained in the changed positions by tlie keys as lon as the latter remain de ressed. Attache to each bar is a latera ly projecting Wing 38. (Figs. 3 and 4), which at each impulse given the bar by a key comes against the up er end of a movable and variably acting lin 39. This link is attached to the segment lever or column actuator by which the corresponding numeral wheel 4l is actuated, and by which the corresponding type segment 42 is positioned properly for printing the amount added. he attachment is preferabl a ivotal one at 39a. A spring 68 acts on t e link and returns it to normal position after each depression. The inovement received by the link from the bar 3l positions the lower end of the link varyingly in accordance with the power of the key by which the bar is actuated, and brings the laterally projecting pin 43 on the link under or in proximity to one of the notches 44 in an arm 45 corresponding to said key. This arm Which is best shown at Fig. 4 and which we call the numeral or graduated arm, is arranged in the denominational line and provided with a series of nine notches 44 corresponding to the keys of the denomination and forming a sort of rack, one notch 4-6 being dee er than the others and a guard 47 being p aced back of notch 46. There is one such arm for each denomination, and the series of them is supported on the rock shaft 48, which we call the main actuator. The numeral arms are positioned on the `main actuator by slotted cross bars 51 and 52 carried on arms secured to the actuator and with the notched portion of the numeral arms 45 projecting forwardly of the main actuator, and their rear ends which are forked straddling the cross rod 49 secured in the ends of arms 50. A spring 97 extends arm 347.

from each numeral arm forwardly and downwardly to the cross rod 97 a also inserted in the arms 50.

The main actuator is rocked by power from a suitable hand lever 55 shown in Fi s. 1, 2 and 8 or other power device by which t e machine is operated. It will be seen from the description thus far given that the rocking of the main actuator which occurs at each str'oke or operation of the power device will im art a vibratory motion through an arc to tlie notched ends of the numeral arms, and such vibratory motions will be uniform 4in extent exce t as they may be varied by the yielding of3 the springs 97. In this v1- bratory movement, the notched or graduated ortion of the numeral arms encounters the pins 43 on such of the links 39 as have been positioned by the striking of the keys, and such pins enter the notches 44, which correspond to the keys struck. With the pins centered in the notches, the main actuator completes the movement imparted to it by. the ower device, and in so doing, carries down tlie arms 45 and the latter carry with them the variable links Whose pins are centered in the notches 44. The variable links give motion in turn to the column actuators, the extent of which is dependent upon the position ofthe notches in which the pins 43 are entered, and because of the variable movements of the links 39, the column actuators are actuated in accordance with the power of the keys and are thus adapted to add the amount represented b the depressed keys upon the register Whee s, and also to position the type for printing the same amount. When the ins 43 stand under the deep notches of tlie arms 45, the vibration of the arms will be idle as the deep notches permit full strokes to take lace without engaging the pins 43. (See Flig. 4.) The guards 47 prevent an tendency by the links to swing too far bacli.

As shown at Fig. 3, represents one of the links connecting the column actuator with the type segment and 66. is a toothed segment on the end of one of the column actuators and meshing with the pinion 67 through which the corresponding numeral wheel is turned, being connected thereto as follows: Said pinion is loose upon the nu- Ineral wheel shaft, and is attached to the side of a disk 115 upon which is a spring pressed pawl 117 adapted to engage a ratchet 118, when not prevented from so doin by the answer rings 113. laterally projecting pin 119 encountering ,a spring stop 120 on the proximate side of ratchet 118. Adjacent to the ratchet is a toothed disk 107, and next to the disk is a separating disk 107EL and adjoining disk 107a is a ring carr `ng either the arm 346 or the 0 these, the ratchet, the toothed disk 107, the separating disk and the arm IIS The disk 115 a so carries a t at when the sha rin are mounted with the numeral wheel on a s eeve 322. merel wheel are more fully described below and illustrated in Figs. 11 to 17, inclusive. The column actuators are pivoted on a rod 190, so that their forward ends in the Inovements described travel through an arc, and they are each provided with a lifting spring, as shown at Fig. 9 Aof the said Felt patent.

The releasing of the depressed keys may be caused by the lever 7() which is pivoted at 71 and shown at Figs. 1, 2 and 8, and has an arm 72 bearing a ainst the upper end of a swinging lever 73oose on rock shaft 74, but operatin said shaft in one direction Vby means o a laterally projecting in 92 engaging the crank 93 fast on the sha t. The lever 73 has a retracting spring 12l, and the shaft 74 extends across the machine,. and is rovided with a number of arms 75 on whic is secured a cross bar or plate 76, having teeth 77 roj ecting upwardly from it.

here is one tooth 77 for each denomina* tion, and each tooth is arranged to bear against a curved portion 7 8 upon a corres ending locking fplate 28 in such manner t is rocked, the tooth will be forced against the curved portion and swing the plate 28 avvayl from its acting position, and thereby cause the release of any keys which may be locked at the time. To effect this release which is given to all the lates, the Alever 7 0 is swung toward the rear rom its intermediate position, The spring 79 attached1 to a depending leg on rock shaft 74 insures the immediate return of the rroc-:lr shaft and parts carried by it to normal position. I' Portions of this same mechanism are utilized ineiecting the release of the keys at the conclusion of each printing operation by the following means; pivoted at 81 is an irre ular shaped plate 8O controlled by the ro ler 82 on cam 56, hereinafter denominated the mais earn, and best show-n atligs. l and 2. A link S3 is attached to this plate and spring 84 draws Vthe link toward theiront of t Ve machine. Upon the upper ed -e of link e 83 is a shoulder 85, which, when t e link is drawn Yrearwardl by the motion received from the cam 56, is engaged by the lower end of lever 73 when the main cam returnsto normal position. When the main cam returns to normal position, it allows the link to return forwardl in obedience to sv ring 84 and in so doing, t e linlr carries the lbver with it for `a short distance and until it slips out of prlxagement by reason of the depressing of 83 by the projecting lip 86 on the lever' 70, the lip beingvin contact with the inclineYV 86a.' This movement ofthe lever 73 rocks shaft 74 Figs. 2,l 3 and 9 sufficienti to releaseV the keys through the medium of t e .teeth 77 and curved Aparts 78 already described. This All these features of the nu- Vswing there awa x keys which may e down at the time will be ster.

desired to repeat numbers, and for this purpose is swung toward thc front of the inachine, and in assuming this position, the erm 72 is so far withdrawn from the lever 73 as to allow the'laiter to rock on its pivot under tho power ol spring lil, and this movement carries the lower end oi lever 73 so far toward the rear of the machine that engagement between it and the shoulder 8.5 is prevented.

and consequently shaft T4 romains idle dnr- Y ing the repeating, and none of the operations above described and usually performed by it take place. The lever is provided with a spring SS which tends to force it into repeatn ing position, and it is normally prevented from assuming that position by a spring catch 89. This catch is readily turned sov as to release the lever when any repeating is desired. The lever is also capable of beincr moved to a third position, and 1t is so mover when the answer or total is to be printed. ln this position, its upper end is moved toward the rear of the machine, and the projection 72 pushes the lever 73 so lar that the hook o the latter sets over the projection and locks the lever in its new position. This lock re mains in force untilreleased by the'link SS upon the conclusion of the answer printing operation. in setting the lever 79 for answer printirjf, the link 94 which connects the free end of crank 93 with the lover end of lever V70, imparts a greater rocking motion to shaft 74 than it receives in the Ways previously described, and in this rocking movement the -plate 76 engages the proximate edges of depending ortions 95 of the cam bars 31 and carries al said bars toward the rear of the machine suiiciently to bring the spaces between the inclines 34 under the keys, so that if the keys are then depressed no result will be produced beyond the idle descent of the key. In this Vsame movement of plate 76, the teeth 77 act on the lockingplates 28 and from the cys, and any released. The link 94 is slotted where it is joined to thev lever 70 Fig. 2 so that the link need. not change position when the lever is set for repeating. The increased movement given the bars 31, as just stated, also casses an increased swinging movement bythe variable link 39 which carries their pins beyond the notched arms 45. As the pins project on both sides of the variable link, they are adapted, when thus positioned, to engage the spring depressed arms 96 Fig. 4 which in some respects are similar-'in size and shape to the arms e5 and are arranged arallel to the latter, and they are support in the main actuster 4S and ositioned by the plates .5i and"Y 52 in :noch t e same way as the arms 45, and each is also provided with a spring 54 attached to cross rod 97a to hold it to the actu- Tlie arms 96 are provided with guards 9S at their extreme ends which act as stops to ros the pins 43 and prevent the links from moving too far when positioned by the cam bar. With this construction and with lever se t as described, we print the totals or answers by operating the main lever or power device 55, which by means of the connecting mechanism described in a later part of this specification, imparts a rocking motion to Ythe main actuator. As already described, this rocking of the main actuator carries the arms 96 downward for variable distances, the springs 54 yielding so that the partial strokes are permitted. The length of the strokes depends on the position of the numeral wheels at the time and the column actuators are arrested when they have moved far enough to position the types corresponding to the numbers exposed on the numeral wheels in rinting position.

When t e lever 70 is set for printing the totals, it carries with it a bar 100 Figs'. 1 and 2. This bar has a slot 101 in which is a pin 102 carried by the lever, the slot being adapted to permit changes in the position of the lever when it is shifted to secure repetitions and to cause the release of depressed keys without affecting the bar. This bar at its forward end is attached to a crank 1 03 on a rock shaft 104 extending across the machine and located over the series of numeral wheels. This shaft is angular so that when rocked, it is adapted to depress the series of locking stop levers 105 pivoted on a cross rod 106 and force them to engage the numeral wheels (Fig. 4.) In thismanner, the numeralwheels are absolutely locked by the setting of lever 70 for answer printing and remain so until released as hereinafter stated.. The stop levers engage the teeth 107 upon the numeral wheels. The shaft 104 and the bar 100 are returned to normal position by spring 109. The series of locking levers 105 is also connected to the answer arms 06 of corresponding denominations bv vertical links 1 55.

(See Fig. 4.) The links are slotted at their upper ends and pins on the levers 105 enter the slots. By this construction the levers 105 are forced to arrest the rotation of the numeral wheels in key printing near the end of the forward stroke of the main lever but before the printing hammers have been released.

The shaft 104 carries at its farther end a cam 111 (Fig. 24) which works in a slot formed in the sliding bar 112, extending across the series of numeral wheels and carrying a series of answer rings 113. There is one of these rings for each denomination and they are adapted to move over the disks 1 15 of which there is one attached to each of the pinions 67 and to hold the pawls 117 on said disks out of action while the pinions and disks are being rotated by the column actuators in positioning the type for answer printing. During this independent operation of the pinions and disks, the numeral wheels are locked by the stop levers 105, as already described. And the rotation continues until the laterally projecting pins 119 on the side of the disks encounter the spring stops 120 Figs. 14 to 15a on the proximate side of the correspondin ratchets 118. These spring stops are eac provided with a pivot 320 extending laterally throu h the ratchet and adjacent parts as lai y seen at Fig. 15". The acting end of t e sto is controlled by a spring 321, one end of t e spring being attached to the stop, and the other end after passing partially around the sleeve 322 is secured around a rivet 323 by which a clip 324 is attached to the ratchet. This spring allows the spring stop to yield to the pin 119 when the latter moves in one direction, but the pin engages said stop so as to carry the ratchet with the disk 115 when the movement is in the other direction. The clip 324 has a point 325 which normally lies over the offset portion of the pivot 320 of the stop, and serves to confine the stop with its pivot in position in the ratchet and adjacent parts.

The heel of the clip 324 normally rests in an annular groove 326 formed in the disk. The rivet 323 holds the clip with sufiicient firmness to prevent the heel from jumping out of the groove, but the attachment is not so rigid as to prevent the lifting of the clip from out of the groove when it is desired to insert or remove the spring stop, the lifting of the clip from the groove carrying the projection 325 away from the pivot of the stop so that the latter can be taken out by a lateral movement. The disk 115 is turned during this independent rotation in the direction in which the stop 119 engages the spring stop and as soon as the engagement takes place, the rotation of the disk 115 is arrested because the numeral wheels are already locked. This arrest takes place sooner or later, according to the -posltion occupied by thenumeral wheel at the time. Thus, if the Wheel stands at 1, the arrest will take place early in the rotation of the disk. If it stands at 2, the disk will be permitted further rotation and at 3 still more and so on. And at the time of the arrest the type Will have been positioned at the printing center in accordance with the numbers shown at the sight opening upon the numeral Wheels so that the totals can be printed by releasing the hammers. The springs upon the answer arms accommodate any further movement of the main actuator after the column actuator and pinion have been arrested, as just described.

Ordinarily when the total is printed, it is followed by an automatic canceling operation in which the numeral wheels are all brought to zero. The mechanism for effecting this canceling is the following. Just before the main lever 55 completes its forward stroke, 'the pin 330 Fig. 25 on cam 56 encoun- IIO ters e trip 33l pivotcd et 332 upon s projection from e lever 333 which we cnil the suhtotzil lever, because in addition to the function here `given it, it is hrought into inen-l nulliY when it is desired to print the totals Without canceling iis descrihed helow. vThis lever is pivoted ststiointriljv st 334. The trip 233i is prevented from swinging on its pivot in one direction by the pin 335 upon the suhtotzil lever so that 'when the pin 330 strikes the trip, it swings the lever 333 toward the rear of the machine. The lever 333 has a. forwardlv extending erin 336, the point 33? of which encounters the lever rocking upon pivot 334 und carrying e pin 339 Working in a slot 340 in the sliding har 100. The swinging movement imparted to lever 338 in this manner lifts the end of the sliding har 10U so that the pin 102 is brought into the lon-er perl; of the slot 101 and no longer holds the our 1Q@ in its rearward position, the lower portion of slot 101 being elongated. This leaves the spring 109 free to act and consequently, the bur is moved forwardly until pin l0? encounters the lower portion of the slot, this return movement, being, however, onlyv a partiel one und without ellcct on the lever it). A spring 341 acts on the lower end of trip 331 lifting it so that it is norrnslly in contact with the pin 335 and the spring 3&2 is attached to the lever 338 and to s projecting point on lever 333 at its lower end,Y und tends to return seid lever after eseh op=V Yeration and through said lever to also return lever 333. The positioning ol lever for sulitotsling will he described later on.

The numeral wheel stop levers 195 are provided with flat surfaces 343 eds ted to he acted upon oy the shaft "194 when itv is turned to force the levers into locking position, and slso with overhsnging horns 344 adapted to he lifted b v the pins 345 which areprovided upon the sheft in slinenient with the stop levers, when the shaft is rotated heck toward its normal osition. The nornie-l position ol the slntft is illustrated et Fig. 4 and its locking` position at Fig. 1l. The partiel stroke ot han* 100 already stated, brings the shaft to s position intermediate between these extreme positions, but in so doing, while it does not shift the answer rings so as to free putvls il?, it does lift the sto levers out of engagement with the miniers wheels so that the latter are again free to turn end do turn hy resson of the engagement between pin l 19 und the spring stop 120. The inion disk carrying the pin 119 is actuated iytlie column actuator, which is pulled down h v the connection 39 receiving' power from erm 9S returning to its rest on the heed of screw 93;* under the action of s ring 97., The nnmersl Wheel revolves unti the arm 346 in the esse oi the unit wheel, or the arm 3l? in esse of the other Wheels, encounters the stop As soon as the wheels are releasedj es instl described, the canceling takes place unless prevented h v the positioning of the subtotal lever as stated below. In this operation, the nuin ersl wheels ere. moved from the positions theiY occupy utI the time h v power exerted on the column iectustors by the s rings 97, which springs lieve been strainedV j the an resting oi the disks 115 as described above.

,i This rotation of the wheels carries the units Wheel to the 0 position and all the others to the 9 position, the Wheels Doing arrested in these positions oy providing the unit-s wheel with s. projecting arm 346 and the other wheels Witlisitnilar arms 347, all adapted to encounter pins 348 u on the answer rings Figs. 1S end 1.9 when t ie answer rings are positioned es in total printing. As will be noted from Figs. 18 and 19, the erin 345 is located differently upon the unit Wheel from elle location given the arms 347 upon the higher wheels, This dillerence in position is one which allows the unit Wheel to move one space farther than the higher ones, carrying it to the 0 position While the others are srrested at the 9 position.

Upon the completion of the forward stroke of the. main lever 55, seid lever immediately cointnences its return and cern 56 likewise commences to return at the seine time. This eem carries a pin 350 Figs. 25 end 28 which in this return movement eneounters as shown et Fig. :28 the heel of s lever 351 which is pivoted stationsrily et 352, and is rovided with s retfracting spring 353.' The orward end of Y the lever engages a. second lever 354, in much the same manner as the corresponding levers of Patent No. 749,17? engage. The rear end of lever 354 is snp ortedupon and attached to the upper-end o .a bell crank 355, pivoted at 356. Normally the levers 351 and 354 are unlstched ss at Fig. 25, but Whenever the com 56 receives its initial forward actuation, tliecpoint 357 on it encounters e roll 35S pivcte on pivot 359 supported in sn erm 350 projecting from the crank 355. The roll may e und is cut sway at one side and carries an arm 361. With this constructiouit will be seen that when the point; 357 encounters the roll, thelstter will he turned about. one third the ver round so that the position of the erin 35i is reversed and in this saine movement, the crank 355 Will he moved toward the front of the machine so es to carry lever into position end alittle beyond where it may engage lever 351. As the pointJ V357 moves off the, roll, it allows the crank to recede partially, und the enge vement between the two levers takes place t ien as shownat Fig. 2. The lever 354 extends to the front of the machine and is pivotelly joined to an srrn 362 mounted upon e shaft 363 and provided et, its lower end with s retrsctin spring 3551. The shaft 353 carries e series o lingers 366, which project downwardly, as seen at Fig. 1 1, and into position Where they loo Ilo

izo

may control the swinging lever 367 supporting the carrying pawls 368.

369 represents the retracting s rings acting on levers 367. When the cran 355 is actuated as above stated, it forces lever 354 toward the front of the machine and in so doing, rocks shaft 363, bringing the fin ers 366 against the levers 367 and carrying t eupper ,ends of the levers so far away from the numeral wheels as to prevent action by the carryinglpawls.

W en the operation just described takes place, the carrying hooks 370 are allowed to drop into position under the power of their sprln s 371 between the levers 367 and the whees, and thus to hold the levers 367 from returning. As soon as this action has taken place, the fin ers 366 are allowed to retreat partially by t e disenga ement of the point 357 from the roll 358, t e retracting spring 364 now brin ing the two levers into fu l engagement. This receding movement allows the fingers 366 to move away from the levers 367 a short distance. The levers 351 and 354 remain engaged as in Fig. 2, however, until near the end of the return stroke of the cam 56, and consequently the carrying pawls remain locked out of action during the same time. When the unit wheel is positioned at the zero position as described above in the canceling operation, and in assing from the 9 to the 0, the cam 372 on t at numeral wheel engages the end of the carrying hook 370 and raises it sufficiently to free it from the lever 367, allowing that lever under the action of its spring to move up a ainst the finger. This movement, however, oes not allow the carrying pawl to move into its acting position. s the main cam nears the conclusion of its return Stroke, it actuates the lever 351, destroying the en agement between said lever and lever 354 so tat lever 354 is free to move back to its initial position, and in so doing, to release the carying lever 367 and permit the carrying pawl to carry the tens numeral Wheel bringing it to 0. This movement of the tens wheel results in a like movement in the hundreds wheel and so on through the series, bringing them all to zero. In the return movement of cam 56, no contact between the projection 357 and roll 358 takes place.

l In the printing of the totals in the ordinary manner, the sub-total lever is swung'back- Ward by the operation of the mechanism at the pro er time and to-prevent its being swung backward by hand atY other times which would tend to cause the printing of a row of nines instead of the figures on the numeral wheels, we provide a safeguard consisting of a lateral fiange 153 Fig. 25 on the forwardedge of the main cam adapted to engage the rearwardly extending arm of the subtotal lever at all times when the lever and main cam are in normal position and at all other times exce t when the main cam is nearing the end of) its forward stroke and has carried the flange to a point below the arm of the lever, leaving the lever free to move rearwardly at the proper time in the operation of the mechanism.

In the cancelingoperation above described, the turning of the tens wheel from nine to zero is dependent upon the turning of the units wheel from nine to zero so as to cause a carrying of the tens wheel. But it often happens that the unit wheel will be standing at zero at the commencement of the canceling, and consequently it remains motionless during that operation, so that other means are 'required for starting the train of carrying mechanisms in operation at such times. These means may be the following; at 13() of Figs. 1 and 2 is a substantially horizontal lever pivoted at 131 upon the releasing lever and shifted whenever the releasing lever is adjusted. A spring 132 tends to draw this lever toward the front of the machine, and upon the front end rests an arm 133, held down by a spring 136 and fast upon a cross shaft 134, this being the shaft upon which the carrying hooks 370 are mounted. When the front end of lever 130 is raised, as presently described, it imparts a rocking motion to shaft 134, and through this motion of the shaft a pin 135 inserted transversely in the shaft resses upon the part of the units wheel ook 37() which lies parallel with said shaft and de resses the same, and thus lifts the inner en of the hook so thatit releases or unlatches the lever 367 and puts the latter in condition to move toward and cause the carrying of the wheel as soon as the lever 367 is released by finger 366. This operation of the carrying mechanism, it will be seen is entirely inde endent of any rotation of the units whee The lever 130 is actuated so as to rock shaft 134 as stated by the following means: Upon the rear end of the lever is a swinging hook 137 having a spring 138 tending to throw its arm 139 against a stop 140. This hook is adapted to be engaged by a pin 141 upon a horn 142 of the main cam 56 when the main cam makes its forward stroke and the hook 137 is in the position which it occupies when the machine is set for total printing, no engagement taking place at other times. This engagement carries the rear end of the lever 130 downward and raises the forward 'end so that shaft 134 is rocked. When the total lever is in the position occupied by it during the key printing operations, the lever 130 is so far toward the front of the machine that pin 141 on cam 56 does not engage hook 137.

The subtotal lever is intended to prevent the automatic canceling following the printing of the totals, and it is adapted to perform this function by moving it from the position of Fig. 2 toward the front of the machine at that no engagement takes place between the Y the lever is positioned as linst stated, and locks Lli t the forward end ol:` the latch an i also for locking the machine tWhile the lever isY the same time that the lever 76 is positioned for total printing. It is provided with an arm 143Fig. 25 having an ofpen slot 144 and into this slot the bent end o a latch 145 pivoted upon a stationary pivot 146 fallsvfhena the lever in its new position. in this changer of position, the trip 331 already'mentioned moves so far toward the front of tle machine as to carry it out of the path of the pin 330 upon the main cam by which it is normally engaged. And by reason of this omission toengage the trip, the train ot operations which we have previously described and which are caused by such engagement, do not take place. In other Words-,the numeral Wheels remainloolred so that the canceling cannot take place. The forward positioning of the subtotal lever also carries a pin 150 Vborne upon it against the inclined surface 151 and lifts lever 130 above its normal position, so

pin 141 on the main cam and the hook l137. The lift' v of the rear end of lever 136i@ ivithoutlect upon the carrying hook shaft. The rear end of latch 145 projects as plainly shown at Fig. 25 so that the pin 330 on the main cam encounters it as the cam nears the end of its forward stroke in the subtotaling o eration. This engagement is ada tedkto dpfree it from its locking eng vement with tliesnbtotal lever so that the ever is then permitted to return to normal position under the power of its spring 152.

In operating the machine properly, the operator should not undertake to change the position of the releasinglever after he has commenced a stroke of the main or .power lever, and to prevent an f such thing, we have provided means for oo king that lever during the operation of the main lever, and

being set b vrhand for total printing. To this end, we connect the releasing lever with a swinging lever by a link 161, Fig. 25. The lever 160 is pivote-d upon a pivot v162- and its motion is llmited by a pin 163 entered in a hole 164 somewhat larger than the pin, said pivot and pin bein inserted transversely in a rocking shaft 165 aving a slotted head to receive the end of the lever 166., This shaft is inserted in the side frame of the machine. The lever llias an overhanging portion 166 at its upper end and this overanging portion is adapted to engage the sector 167 upon the side of the main earn 56 when the releas' lever is set for the normal key printing, an during that time it prevents any setting of the releasing lever forn total printing, because auch setting would bring the overhang against the edge of theV sector, and when the releasing lever is set for total printing, itcauses the locking lever 165 i to move from the osition ven in full lines at Fig. 25 to that s own in otted lines inthe same liguregand in this position 'wne'n'the main lever `is omznated.J the overhang rides op on an incline 1768 and falls behind sector 16'? and follows said sector until the Inain cani nears the conclusion of its return stroke. In this return stroke, the overhang 1s corn pelled to return to its normal position shown at Fig. 25 by the inclined cut or slot 169 V 1t will also be noted that While the totallever Yis being moved by hand from one position to the other, the overhanging portion of lever 16@ is over the end of sector 16'? soY that the Inain cam `will be locked. i

Eine Vprinting Vhammers are Vshown at 170 Figs. Z1 to 23 .and swing upon the shaft 171. They are actuated by upon heads 173 also pivoted upon shaft 171 and bearing upon the top of the hammers. stop rod 174 extends across the series of hammers and limits the stroke of the heads 173. The springs 172 are attached to a swinging adjuster 175 provided with ad'usting screwr 176 whereby the tension o the springs 172 is regulated. The hammers are normally held by triggers 177 which are released by releasing frames 178 and are raised after each printing operation by a Swingin frame 179. The triggers are provided spring-s 186. The eads 173 are made separate om the hammers for the pu osos set forth in the patent to l). E. Felt, No. 661,121 of Nov. 6, 1900, but in the present invention five have improved upon the patented construction by adding in the case of each hammer, a spring 181 attached at one end to the Ahead 173 endet the other to the hammer.

In the patented construction, it was found that the hammer sometimesgnade what are called in Shop parlance, double printing, that is, they would strike the paper more than once andl thus leave a blurred impression. The

Y'spring 181 is adapted to prevent this. The

construction of the releasing frames and their inode of operation is fully set forth in patent *reisen No, 644,287 of Feb. 27th, 19Go.

" *t 185v are spring push buttons, one for nach denomination. These; push buttons are adapted to bear upon thetail ends 186v 'ofthe carrying pawls 368 when it is desired to subtract instead of add. The mode of springs 172 acting IIU operation of these push buttons will be fully understood from the patent to Felt, No. 465,255, dated December 15, 1891.

In the said Felt patent No. 749,177, the main actuating lever is attached directly to the main cam, but in the present invention We-have interposed between the lever and the registering and printing mechanism of the machine asprin cushioning mechanism, and a governor a apted to revent the shocks to the registering and prmting mech-` anisms which would attend violent or too quick operations of the main lever. This mechanlsm will now be described and is best' shown at Figs. 5 and 7. Said power device is mounted upon a shaft 200 extending acrossthe machine and carryin at its further end a crank 201. This cran is pivotally joined toa rod 202 in which a cross pin 203 is secured, such pin serving as means for the attachment to the rod 202 of a series of? springs 204, 205 and 206. The rod 202 a uts against a shorter rod or bar 207 to which a sleeve 208 is attached. This sleeve extends over and incloses the rod 202 for the major portion` of its length. The rod 207 also carries a crosspin 209 to which the other ends of the springs 204, 205 and 206 are attached. The springs 204 and 205 are preferably located, one above and one below the rods 202 and 207, and the sprin 206 prefer-l ably encirclesthe sleeve 208, 's arrangement and series of springs being adopted in. order to obtain the desired spring power' Without giving the combined structure an great horizontal width. The bar 207 1s Joined to a crank 210 on a shaft 211. The` main lever receives a forward stroke or irnpulse from the operator when the amount is effected, as will be understood from the description given' in a subsequent part of this specification. The speed of the movement thus imparted to` the cam shaft is, however, controlled by a overnor 220 located at the rear of the mac 'ne and mounted between crank arms- 249 fast upon theshaft 218. Shaft 218 also carries a crank 217 which is connected toaI crank 210 by a link 21 The" governor is movable in a vertical direction, being lifted by the crank 219 by the power received from the springs. The piston221 ofthe vernor is mounted upon the stern- 222 and t e stem is pivotally attached to a stationary part of the machine at 223. Two ports 224- and 225 are'formed in thepiston and are preferably covered by an overhangingplate 226 so that the movement of "mg mechanism and ada Ithe fluid. through the ports is somewhat restricted. One of the ports is provided with a ball valve 227 which closes when the governor is-lifted by the crank and opens when the governor is moving'down. It will thus be noted that the Huid in the overnor moves up through the pist'on whichl is stationary at a much slower rate than it moves down therethrough. The lstem passes through a stuffing box in which. 228 represents the packing, 229 aspring for com ressing the packing, and 230 a nut threa ed in the mouth of the box and confining the spring and packing. The construction thus far described allows the main lever 55 to make uniform strokes and thereby to store u power in the springs 204, 205 and 206, wiich is then exerted in actuating shaft 211 at such speed as is permitted by the overnor, and by this construction, I avoid in]ury to the machine which would attend the giving of unduly quick or sudden movements of the main lever.

The movement of the main actuator is taken from the same crank 210 which actuates the main cam and' the means employed for this purpose are the following; A link 212 extends from the swinging end of crank 210 to a segment 213 mounted loosely upon shaft 200 and a portion of this segment is toothed and meshes with a crank gear 214 upon4 a shaft 215. A link 231 extends from the crankwheel 214 to a crank 232 fastupon the main actuator 48. The segmental rack is adapted to turn the pinion 214 throughsomething. over a half revolution and'thereby it os- -cillates or rocks the shaft 48 as will be under- `spring 235, the other end of which is attached to a. stationary pin 236. This lever will be swun by the segment so that power will be storer in the spring 235 wherewith to start the segment on its backward movement as soon as the power from tli'e crank 210 ceases.
